Description
Experience the next level of power with the EVE 40PL, a tabless 21700 cell that delivers an astounding 70A continuous discharge and 4000mAh capacity. This 4-pack is built for the most extreme applications: high-performance e-scooters, heavy-duty cordless tools, competition-level, and high-output RC models. The tabless design slashes internal resistance to near-unbeatable levels, virtually eliminating voltage sag and heat build-up under massive loads. The flat top fits all standard 21700 spring-contact devices and is perfect for spot-welding into custom high-current packs. When your project demands maximum current without sacrificing capacity, the 40PL is the ultimate power solution.
Key Features
-
70A Continuous / 120A Pulse Discharge – Unleash massive current for the most power-hungry devices. Handles super-sub-ohm builds, angle grinder start-ups, and e-scooter hill climbs with ease.
-
Tabless (All-Tab) Technology – Reduces internal resistance to ~8mΩ, minimizing heat and ensuring instant power delivery. The cell stays cooler and hits harder under sustained loads.
-
4000mAh High Capacity – Remarkable energy density for a high-drain cell. More runtime than typical 3000–3500mAh high-power cells, reducing the need for frequent recharges.
-
Flat Top Design – Compatible with all standard 21700 spring-contact chargers, flashlights, and battery trays. Ideal for spot-welding nickel strips in custom battery builds.
-
4-Pack Convenience – Perfect for building a high-current 2S2P pack, powering dual-battery mods, or equipping a set of heavy-duty tools.
-
EVE A-Grade Quality – Rigorously tested for consistent performance, low self-discharge, and long cycle life. Trusted by professionals worldwide.
Parameters
Applications
Recommended For
-
High-Performance E-Scooters & E-Bikes: Build compact, high-power battery packs (e.g., 10S1P or 10S2P) that deliver massive acceleration and hill-climbing torque. Always use a BMS rated for at least 100A.
-
Heavy-Duty Cordless Tools: Angle grinders, circular saws, rotary hammers — the 40PL provides the current headroom these tools demand without voltage sag.
-
Competition Vaping: Super-sub-ohm mechanical mods and high-wattage regulated devices (builds down to ~0.06Ω) benefit from the near-zero voltage drop and massive pulse capability.
-
Extreme-Output Flashlights: FET-driven hot-rod lights and multi-emitter searchlights that pull 40–60A on turbo can run at full brightness with this cell.
-
RC Cars, Boats & Drones: Professional racing models requiring instantaneous 100A+ bursts.
-
DIY High-Current Projects: Portable spot welders, high-power inverters, and any application where both current and capacity are critical.
Not Recommended For
-
Low-Power Long-Runtime Devices: Solar lights, wireless sensors, and clocks. The 40PL is overkill; choose a 5000mAh low-drain cell like the Samsung 50G.
-
18650-Only Devices: This is a 21700 cell (21mm x 70mm) and will not fit.
-
Standard USB Power Banks: The extreme performance is wasted in a 5V/2A application.
FAQ
Q: Is the 70A rating continuous? Some sources list 60A.
A: The EVE 40PL is rated for 70A continuous discharge. However, to maximize cycle life and keep the cell well within safe temperature limits, many builders design their systems for a 60A continuous ceiling. The cell is fully capable of 70A; just ensure proper cooling if you plan to run at that level continuously.
Q: What does “Tabless” mean and why is it better?
A: A tabless (or all-tab) design eliminates the traditional thin metal tabs connecting the electrode layers. Instead, the entire edge of the electrode is directly connected to the terminal. This drastically reduces internal resistance, minimizes heat, and allows for much higher current delivery with less voltage sag.
Q: Can I use this for vaping? What’s the lowest safe resistance?
A: Yes, the 40PL is a top-tier choice for extreme sub-ohm vaping. With 70A continuous and 3.6V nominal, it can safely handle builds down to approximately 0.05Ω, but this is at the absolute limit. We recommend staying at or above 0.07Ω and always calculating your current using Ohm’s law. The 120A pulse rating provides additional safety headroom for short draws.
Q: Do I need a special charger for tabless cells?
A: No. The 40PL charges just like any other 21700 lithium-ion cell. Use a quality CC-CV charger. Charging at 0.5C (2A) is recommended for longevity, though it can accept up to 4A.
Q: How should I store these cells?
A: Store at 3.6–3.7V (~40–50% charge) in a cool, dry place using non-conductive battery cases. Avoid storing fully charged or fully discharged for extended periods.
